Abstract
The utility model belongs to the technical field of air compressors and particularly relates to a linear reciprocating double-cylinder air compressor. The linear reciprocating double-cylinder air compressor comprises an air compressor main body and two air cylinders, wherein the two air cylinders are symmetrically arranged on two sides of the air compressor main body, pistons are arranged in both the air cylinders, one of the pistons is hinged to one end of an inner connecting rod, the other end of the inner connecting rod is hinged to a crank arranged in the middle of the air compressor main body, the outer sides of the two pistons are fixedly connected with two outer connecting rods which are arranged symmetrically, and the axis of each outer connecting rod and the axis of the inner connecting rod are arranged in the same plane. A driving main shaft drives the crank to rotate so as to drive the outer connecting rods and the two pistons to achieve synchronous linear reciprocating motion through the inner connecting rod. Due to the fact that the inner connecting rod drives the pistons to motion, lateral force of the pistons driven by the inner connecting rod on the air cylinders is reduced, stable power is provided, the air compressor is made to motion stably, collision and abrasion of each part are reduced, and the service life of the air compressor is prolonged.
Description
Technical field
The utility model belongs to the air compressor technical field, refers in particular to a kind of linear reciprocating twin-tub air compressor.
Background technique
Air compressor is the machine that a kind of pressurized gas improves gas pressure, it is widely used in mining industry, metallurgical industry, machine building industry, petrochemical industry, medical treatment, weaving, food, agricultural, traffic, freeze in engineering separated from the gas and the national defense industry, the integral structure that the piston of present compressor is connected to form by crankshaft-link rod, the driving component that passes the crankshaft-link rod center hole connects the crank of a side, the crank to-and-fro motion drives the motion of crankshaft-link rod one-piece piston, because the movement locus of crank and piston is not or not same plane, the piston that crank drives is many to the lateral force of cylinder, cause compressor abrasion and vibrations easily, have a strong impact on the working life of air compressor.
Summary of the invention
The purpose of this utility model provides that a kind of piston is few to the lateral force of cylinder, linear reciprocating twin-tub air compressor stably moves.
The purpose of this utility model is achieved in that linear reciprocating twin-tub air compressor, comprise the air compressor main body, two cylinders that are symmetricly set on air compressor main body both sides, be provided with piston in the cylinder, wherein, one end of described two pistons one of them and inside connecting rod is hinged, the crank at the other end of inside connecting rod and air compressor main body middle part is hinged, the outside of two pistons is fixedly connected by two symmetrically arranged outside connecting rods, the axis of two outside connecting rods and the axis of inside connecting rod are on the same plane, and drive main spindle drives the rotation of crank and then drives outside connecting rod and two synchronous straight reciprocating motions of pistons realization by inside connecting rod.
According to the linear reciprocating twin-tub air compressor of the above, wherein, the articulating point of described inside connecting rod and piston is positioned on the axis of piston.
According to the linear reciprocating twin-tub air compressor of the above, wherein, described outside connecting rod is " worker " font, and it is circular-arc that bent intermediate is, and the upper and lower end of " worker " font is provided with the mounting hole that is connected with piston.
The utility model gives prominence to compared to existing technology and beneficial technical effects is: inside connecting rod drives piston motion, reduced the lateral force of the piston of inside connecting rod drive to cylinder, power stably is provided, make the air compressor motion steadily, reduce the gouging abrasion of each parts, improved the working life of air compressor.
